COTONEASTER, a genus of the rose family (Rosaceae), containing about twenty species of shrubs and small trees, natives of Europe, North Africa and temperate Asia. C. vulgaris is native on the limestone cliffs of the Great Orme in North Wales. Several species are grown in shrubberies and borders, or as wall plants, mainly for their clusters of bright red or yellow berry-like fruits. Plants are easily raised by seeds, cuttings or layers, and grow well in ordinary soil.
